Binary inputs
The TCU contains two galvanically isolated binary in-
puts, BIN 0 (connection 12) and BIN 1 (connection 13),
both inputs share a common ground (connector 11).
The switching device must be able to supply 12–28
VDC / 10 mA to the binary input. The connection prin-
ciple of binary inputs is shown in Fig. 9.
